different perfect pass displays

They can set you up with any of them, pretty sure. The combo gauge won't work with our 2 PPR tach signal without a freq. doubler which I could design

Here's the second page. The MB sports one looks just like our gauges with the illumination and everything. I think they can send you stuff before it get's logo'd.  Check first, they're flexible.

Pete, assuming those combo gauges are RPM and not MPH....the MB Sports one with a doubler is exactly one half of the damn near perfect deal. Replace the stock tach with the PP Pro Combo gauge. Use the doubler output as the RPM input for the Accuski. Use Paddlewheel speed for both PP and the Accuski. Might have to have the Accuski reprogrammed, right??

This way, we'd have outstanding RPM display on our existing speedo, the souped PP combo indicator for tach, while keeping the temp/pressure/tank indicator and the Accuski message center for depth and engine hours (we'd be giving up the cool hour meter on the stock tach).

Accuski could do paddlewheel speed ifwe doubled the tach input, right Pete?

I think you'd want to have the stock tach signal going to the MMDC, but it probably doesn't matter. I don't know what the MMDC wants for a pulse input, or how to change it from stock speedo input to using the pulse input. The guys at Accuski could tell you. Thinking about it, I don't know if I want to mess with the tach input with a doubler, I would have no way to test it.
 I just pulled my stock speedo. I now have three tachs, one on PP, one in the dash and one in the Accuski module.

You should just get one of the small standalone gauges and make a small carpeted panel to mount it in.
